Astronauts are trained individuals who spend a considerable amount of time in space and are in charge of maintaining space stations as well as satellites. Astronauts are generally trained for more than 2 years to be able to withstand the climatic and air pressure difference when they travel to outer space. Astronauts are also in charge of studying various extraterrestrial objects such as asteroids, galaxies, meteors etc. 

In order to become an Astronaut after 12th, students must pursue both undergraduate and postgraduate Aeronautical Engineering Courses or Astrophysics Courses or any other courses that are related and relevant to the field. Some of the other top courses that can be pursued to become an Astronaut are BTech Space Technology, BTech Aeronautical Engineering, MTech Aeronautical Engineering etc. Check: How to Become an Astronaut in NASA

India is home to some of the top Aeronautical Engineering Colleges such as IIT Kanpur, Madras Institute of Technology, IIST Thiruvananthapuram, Anna University etc. Admissions to these colleges are done on the basis of various Engineering Entrance Exams such as JEE Main, JEE Avanced, GATE etc. The average annual salary of an astronaut ranges between INR 10 LPA – 12 LPA.

What does an Astronaut Do

Astronauts are trained to pilot and/or travel in a spacecraft, work in space, and do activities related to human space exploration. Though space travel seems like a cakewalk these days, it is a line between success and failure. Most of an astronaut's career is spent undergoing extensive training. Some of the duties of an astronaut are listed below:

  • Preparing for spacewalks to install new equipment or perform maintenance tasks in space
  • Researching new technologies that could be used in space exploration or in space habitats
  • Communicating with mission control to report on findings or issues that arise during the course of the mission
  • Conducting tests to determine how well crew members can perform their jobs under stress
  • Conducting robotics research and development in collaboration with engineers on Earth
  • Conducting scientific experiments in space to help scientists better understand phenomena in microgravity environments
  • Preparing for emergencies such as fires, depressurization of cabins, loss of oxygen supply, loss of communication with Earth, solar flares, and other threats to the safety of astronauts and the mission

Types of Astronauts

Astronauts have their specific roles in outer space for the success of any mission. The astronauts are classified as per their field of expertise some of which are mentioned below:

  • Commander: The main job of a Commander is to check the overall mission success from the begining to till the end, i.e. from the launch of the spacecraft to landing it safely back on the surface of the earth. The Commander is in charge of maintaining the safety of every crew member along with the safety of the spacecraft and all pieces of equipment present on it is the commander’s responsibility.
  • Pilot: Pilot, as the name suggests is the most important designation in an Astronaut’s career. The pilot is responsible for controling every movement of the spacecraft including the launch and landing. The pilot is responsible for controlling the spacecraft as per the mission and taking it precisely to the locations decided.
  • Flight Engineer: The Flight Engineer assists the commander and the pilot efficiently. It’s his job to look out that all the pieces of equipment on the spacecraft are working properly and in any case repair them, fix all the issues and make everything working properly.
  • Mission Specialist: The Mission Specialist is the person sent to outer space for research purposes and he has to collect all the information and analyze everything he is supposed to. The Mission Specialists are experts in their respective fields whether it is geology, biology, chemistry or any scientific field.

How to Become an Astronaut in India 

Candidates who want to make their career as an astronaut can fulfil their dream by pursuing Bachelor’s, Master’s and Research level courses in Aeronautics, Astrophysics, Aviation, Aerospace, Aeronautical Engineering etc. Many universities and colleges are available in India to offer these courses. 

For seeking admissions to Bachelor’s Degree courses in Science or Engineering stream, students must have one of the subjects relating to the STEM field in 12th class. Candidates who have a degree in Aerospace Engineering or Aeronautical Engineering will be an advantage for future Indian astronauts.

Students must have essential knowledge of Science (Physics, Chemistry, Geology), Engineering, Technology and Mathematics. Students can also go for various internships during their study period and gain extensive knowledge related to the career which might prove helpful to candidates in future.

How to Become an Astronaut in India after 12th
